Nice, I call that a win! I'd be curious if the better lighting alone in the same system would produce a greater yield even without imposing a stressor. That is very cool, congratulations, I look forward to the results of the next harvest. BTW, I think you have a lovely 'studio' ;-)
I think you're right. Adding more light to the system will probably be all that's needed to produce more tubers. I didn't show it but one of the plants produced maybe 20 stolons, some of which had tiny (
Very nice experiment. Do you know if they people who did this in 1940 used air pumps or did they do a purely passive method? I think Kratky grew potatoes with his method without using an air pump, here is some scant info on it. As you say maybe the surface area to volume ratio of the lower container is an issue. cipotato.org/wp-content/uploads/Seminars-archives/0822_Bernie%20Kratky_summary.pdf
Gericke didn't use an air pump, I assume because his basin was much shallower. This may have meant the surface area to volume ratio was such that sufficient oxygen could diffuse into the solution. I suspect that active aeration would be unnecessary in a properly designed system. Thanks for the info, I'll check it out.
